It is probably good. You have to look at the preceding text to be sure: what tests failed? Is that expected? Ideally there would never be unexpected failures. But for example many guality tests have failed since forever; some tests are by nature quite fragile, so those *tests* need (time-consuming) maintenance while the compiler itself is fine; and for example some tests fail because some *other* installed software is buggy (libc, gdb, as, etc.) So there will often be a few testsuite failures. Look at the actual failing tests to see if this is bad. You can also compare with published results (on gcc-testresults@) to see if some failure is unique to your situation. Segher
